Fluid dampers, hinges and freezers

Abstract

A fluid damper, a hinge with a fluid damper, and a freezer with a fluid damper, the fluid damper includes: a housing; The rotor in the casing, a fluid chamber is formed between the inner peripheral surface of the casing and the outer peripheral surface of the rotor, and the fluid chamber includes an open side end surface continuous in the rotation direction of the rotor, a radial surface and a closed-side end surface, and the fluid chamber is filled with working fluid, wherein, at the fully closed position, there is a reserved space between the rotor and the closed-side end surface of the fluid chamber. According to the fluid damper of the present invention, at the fully closed position, there is a reserved space between the rotor and the closed-side end surface of the fluid chamber. Accordingly, even when the fluid damper is closed immediately after being opened from the fully closed position, the fluid damper can sufficiently exert a damping effect because the working fluid exists in the reserved space.

Description

technical field [0001] The present invention relates to a fluid damper, a hinge with a fluid damper and a freezer with a fluid damper. Background technique [0002] In the past, fluid dampers were often used in order to avoid the noise caused by the sudden collision with the main body of the freezer when the lid of the freezer was closed. [0003] A fluid damper generally includes a housing and a rotor, wherein the housing has a bottomed cylinder with one end open and a cover that closes the open end of the bottomed cylinder. The rotor is rotatably disposed in the housing and has a rotating shaft and a The valve core is movable, and a fluid chamber is formed between the bottomed cylinder, the cover and the rotor, and the fluid chamber is filled with working fluid. [0004] In the fluid damper, when the rotating shaft rotates in the first direction and the spool is in the closed state, the working fluid tends to be compressed and a load is applied to the rotating shaft. On t...

AI Technical Summary

Problems solved by technology

In this case, since the fluid of the fluid damper is almost all concentrated on the open side of the fluid chamber, the damping effect cannot be exerted, resulting in the collision of the freezer lid and the freezer body to generate noise
